SHOCK-COMPRESSOR.

SPECIFICATION forming part of Letters Patent No. 698,735, dated April29, 1902.

Application filed December 7, 1901. Serial No. 85,047. (No model.)

To 0. whom it may concern.-

Be it known that I, SAMUEL RAPP, a citizen of the United States,residing in Pleasant township, in the county of Madison and State of Ohio, haveinvented certain new and useful Improvements in Shock-Compressors; and Ido hereby declare the following to be a full, clear,- and exactdescription'of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

The object of my invention is to provide an improved device whereby theoperation of binding shocks of corn can be performed with neatness,thoroughness, and despatch.

The invention consists in a novel construction of such a device wherebythe compressing or drawing-up rope which passes around the shock can bepulled with approximately an equal pull at both ends, so as not todisturb the original relative arrangement of the stalks in the shock.

In the accompanying drawings, Figure 1 is a top view showing relativeposition of the parts when the device is in use, a small portion of theframe being broken out. Fig. 2 is a view of the front or lower side ofwhat is shown in Fig. 1.

In the views, 1 designates a case or frame shaped, preferably, out ofmetal and comprising an extended flange or wall 1 at its rear side, twoparallelly-arranged plates 1 and 1, standing at right angles to the wall1, and a bracket-arm 1. Journaled in opposite ends of the frame betweentheplates 1 and 1 and the bracket 1 and the plate 1 are grooved pulleysor other abutments 2 and 2, respectively. Pivoted on a common pin 5,between the plates 1 and 1 and approximately equidistantly between theabutments 2 and 2, are the shanks of two clamps 3 and 3 having theirtoothed or roughenedheads turned toward the peripheries of the-abutments2 and 2. Connecting the shanks of the clamps is a coil-spring 4, tendingto draw the toothed or roughened heads of the clamps toward theabutments. The ends of the rear wall of the frame are shown to berounded or flared rearwardly to permit the rope hereinafter referred toto run easily through the devlce.

In the practical use of this invention a rope 7 (shown in dotted lines)is knotted at a sufleased.

The device is now ready to be used in compressing a shock. The long endof the rope is passed around theshock at about the place where theshockis to be tied and then inserted or placed between the clamp 3 andthe pulley 2, the head of said clamp being drawn away to permit suchinsertion by a manipulation of the thumb-piece 3 on that clamp. Tocompress'the shock, each end of the rope is taken in a hand and drawnwith sufiicient force to tightly compress the stalks of the shocktogether. Simply liberating these ends suffices to insure their beingcaught and held in the drawn-up condition, because the coilspringconstantly tends to force the clamps against the rope, and the rearwardtension, due to expansion of the shock, immediately effects the lockingof the rope in the position to which it has been drawn up. When this hasbeen done, the operator is at liberty to take and place his tying-twinearound the shock and tie the same, with the assurance that the shockwill not be accidentally re- When the shock has been tied, he removesthe compressing-rope by withdrawing the clamp 3 and lifting out the freeend of the rope, and this same operation can in like manner be repeatedwith all the shocks.

I am aware that a number of devices have between my invention and whathas preceded me in the prior art.
